02/17/2020 – Ephemeris – A look at Orion and his hunting dogs

February 17, 2020 Comments off

Ephemeris for President’s Day, Monday, February 17th. Today the Sun will be up for 10 hours and 32 minutes, setting at 6:13, and it will rise tomorrow at 7:39. The Moon, 2 days past last quarter, will rise at 4:27 tomorrow morning.

The great winter constellation or star group Orion the Hunter, is located in the southern sky at 9 p.m. His elongated rectangle of a torso is vertical. In the center of the rectangle are three stars in a line that make his belt. As a hunter, especially one of old, he has two hunting dogs. The larger, Canis Major can be found by following the three belt stars of Orion down and to the left. There lies the brilliant star called Sirius, also known as the Dog Star. It’s in the heart of a stick figure dog lower in the south facing Orion that appears to be begging. Canis Minor is just two stars found by extending Orion’s shoulder stars eastward where we find bright Procyon, the little dog star in the southeast.

The times given are for the Traverse City/Interlochen area of Michigan. They may be different for your location.

02/13/2020 – Ephemeris – Orion’s Belt stars

February 13, 2020 Comments off

Ephemeris for Thursday, February 13th. Today the Sun will be up for 10 hours and 21 minutes, setting at 6:07, and it will rise tomorrow at 7:45. The Moon, 2 days before last quarter, will rise at 11:48 this evening.

Orion’s belt of three stars is one of the most noticeable star groupings in the sky. There are no other group of three bright stars in a straight line visible anywhere else in the sky. The star’s names from left to right are Alnitak, Alnilam and Mintaka. They are actually a bit farther away than the other bright stars of Orion. Alnilam, the center star is over three times the distance of red giant Betelgeuse above them and over twice as far as blue white giant star Rigel below them. Alnilam is 375 thousand times brighter than the Sun according to the SIMBAD Astronomical Database. These three stars were also known as Frigga’s Spindle by the Norsemen. Frigga also known as Freya is the goddess from which we get the name of the day of the week Friday.

The times given are for the Traverse City/Interlochen area of Michigan. They may be different for your location.

02/07/2019 – Ephemeris – Siriusly, folks.

February 7, 2019 Comments off

Ephemeris for Friday, February 8th. Today the Sun will be up for 10 hours and 7 minutes, setting at 6:01, and it will rise tomorrow at 7:52. The Moon, half way from new to first quarter, will set at 9:48 this evening.

At 9 in the evening the great constellation of Orion the hunter can be seen in the south. Its large rectangle of bright stars is now upright, while in the center is a row of three stars, his belt. These stars tilt downward to the left to a very bright star merrily twinkling in the south-southeast. This star is called Sirius, also known as the Dog Star because it’s in the heart of Orion’s larger hunting dog, Canis Major. It is an arc light white star as seen in binoculars or telescope. It’s a neighboring star, just twice the distance of the closest star to the sun at 8.6 light years. It’s name, Sirius, has nothing to do with a dog, but is from the Greek meaning scorching for its brightness or sparkling, due to its intense twinkling.

The times given are for the Traverse City/Interlochen area of Michigan. They may be different for your location.

01/19/2018 – Ephemeris – Orion’s large hunting dog

January 19, 2018 Comments off

Ephemeris for Friday, January 19th. The Sun will rise at 8:14. It’ll be up for 9 hours and 19 minutes, setting at 5:33. The Moon, 3 days past new, will set at 8:15 this evening.

The brightest star-like object in the evening sky is Sirius, also known as the Dog Star. It also is the brightest night-time star in our skies period. Tonight at 9 p.m. it’s located low in the southeastern sky. The Dog Star name comes from its position at the heart of the constellation Canis Major, the great dog of Orion the hunter, which is seen almost like he’s begging, feet to the right. The three stars of Orion’s belt tilt to the southeast and point to Sirius. The name Sirius means ‘Scorcher’, a reference to its great brilliance and twinkling. To me it has a blue tinge like an arc light in a telescope. Its Egyptian name was Sothis, and its appearance in the dawn skies in late June signaled the flooding of the Nile, and the beginning of the Egyptian agricultural year.

The times given are for the Traverse City/Interlochen area of Michigan. They may be different for your location.

12/11/2017 – Ephemeris – Orion rising

December 11, 2017 1 comment

Ephemeris for Monday, December 11th. The Sun will rise at 8:09. It’ll be up for 8 hours and 52 minutes, setting at 5:02. The Moon, 1 day past last quarter, will rise at 2:22 tomorrow morning.

Off in the east-southeast at 9 in the evening the great constellation of Orion will be seen. This is the most famous of all constellations world-wide. We think the Big Dipper is a big deal. It’s not even a constellation, being the hind end of the great bear Ursa Major. Also it’s invisible if one travels far enough south of the equator. Orion is now a rectangle of stars tilted to the left as he rises. With three stars in a straight line in the center, his belt. They are aligned nearly vertically. Orion is a giant hunter. The rectangle depicts his shoulders and knees. Among its other bright stars Orion contains two of the brightest. The upper left star is the famous red giant star Betelgeuse. The lower left star is the blue-white super giant Rigel.

The times given are for the Traverse City/Interlochen area of Michigan. They may be different for your location.

Note to Blog readers

As you probably know these posts are transcripts of my Ephemeris program.  The length of the program is exactly 59 seconds, and the first paragraph takes approximately 14 of those seconds.  So I don’t have much time for the topic at hand.  Therefore I dole out information in rather small spoonfuls.  I’ll be revisiting Orion many times over the winter, talking about the other stars, and wonders found among its stars, also its mythology.   If you can’t wait, type Orion in the search bar for all the past programs on Orion.  Don’t be surprised that much of the programs don’t change much from year to year.  I post the week’s worth of Ephemeris program MP3s on my monthly website http://ephemeris.bjmoler.org/ under the Audio link.

Sunday night and into the wee hours of Monday morning is the time I usually write and record the programs for Tuesday through the next Monday.  Blog postings are prepared the night before the air date.

 

12/04/2017 – Ephemeris – Orion rising in the moonlight

December 4, 2017 1 comment

Ephemeris for Monday, December 4th. The Sun will rise at 8:02. It’ll be up for exactly 9 hours, setting at 5:02. The Moon, 1 day past full, will rise at 6:32 this evening.

Now that the Moon is quite bright and making the fainter stars in the constellations harder to find, let’s look at one of the bright stars of Winter. Tonight at 8 p.m. the bright reddish star Betelgeuse is low in the east, but will be rising higher and moving slightly southward, as the rest of the bright stars in its constellation of Orion the hunter also clear the horizon. To its right are a nearly vertical line of three equally spaced stars, Orion’s belt. Betelgeuse is in Orion’s shoulder. The name Betelgeuse is a corruption of the Arabic phrase “Armpit of the Central One”, although there’s some debate about that translation. Betelgeuse is maybe only 7 million years old, but due to its great mass of up to 20 times that of the Sun, is already dying.

11/20/2017 – Ephemeris – The Moon is near Saturn tonight and the approaching signs of winter

November 20, 2017 1 comment

Ephemeris for Monday, November 20th. The Sun will rise at 7:46. It’ll be up for 9 hours and 23 minutes, setting at 5:09. The Moon, 2 days past new, will set at 7:04 this evening.

Tonight the two day old Moon will appear near Saturn. The ringed planet will appear to the left and a bit below the thin crescent Moon before they set about an hour later. The approaching winter season and the resumption of standard time have dropped sunset to 5:09 in the Interlochen/Traverse City area. Our sunset will drop another 11 minutes before slowly recovering 19 days from now. Two to three hours later another sign of the approaching winter season will appear, as the constellation of the giant hunter Orion rises in the east. He is resplendent with his nearly vertical belt of three stars rising, framed to the left and right by the bright stars reddish Betelgeuse and bluish Rigel. He will dominate our evening skies until April.
